Wow, have you ever wondered if you can see light travel?

Saw this and it sort of took my breath away..............

I work on a very similar laser to the one he uses, 90,000$ for the baseline femtosecond laser alone.

Very awesome, I saw this yesterday, really interesting to watch!

Anyone liking this will really like the "Light-In-Flight" technique of Nils Abramson from the late '70s or early '80s. He used picosecond pulses and holography to make animations of a wavefront in flight.

Do you have a link to where it could be found? Nils Abramson doesn't turn up many results in a search query.

Why $90,000 for a femtosecond system? Isn't it a fairly ordinary Ti:S?

I was about to post the same TED link. Nice video!

[flecom]

so am I an idiot or do the ripples going the wrong way indicate that they are going back in time?

[helium]

Whoever said the ripples were to go the right way, is wrong. Interesting video, thanks for posting this Scoot.

Perhaps it's like Electron current flow?
